@DevilCat666: That's to be expected. The hack waits 2s after the reader opens before doing anything. You can probably add another second to that to actually switch the screensaver, and that's with a cache hit
.
@Leir: Hmm. For some reason, it looks like the timestamp of the last access doesn't get updated on your device... Is the Home screen sort by 'Recent' working properly on your device? Is the date/time set properly? (IIRC, it looked okay in the logs, but I did catch some weird error messages about the catalog that may be related...).
Does it work properly with other books?
